FAQ

Q1: How do I confirm this part is correct for my specific Caterpillar C13/C18 engine?
A: The most reliable method is to cross-reference the part number stamped on your original, failed injector sleeve or listed in your engine’s official service manual with our listed OEM numbers (2274236, 2634920). Providing your engine’s serial number to our technical team can also help confirm fitment.

Q2: What is the primary function of the fuel injector copper sleeve?
A: The copper sleeve acts as a seal and a thermal conductor. It seals the injector in the cylinder head to prevent combustion gases and fuel from leaking. Its copper material efficiently transfers heat from the injector to the cylinder head, helping to manage operating temperatures.

Q3: Are any special tools or procedures required for installation?
A: Yes, proper installation is critical. It typically requires specific driver tools to press the sleeve into the cylinder head bore without damaging it, ensuring it is seated at the correct depth. We recommend referring to the Caterpillar service procedure or consulting a qualified technician. Incorrect installation can lead to leaks and engine damage.
